What is a context window, in simple words?

Think of the context window as the model's desk. Everything it needs for this answer has to fit on the desk at once: your instructions, the conversation so far, any documents you pasted, and the answer it's writing.

SuperCosmos's desk is big: 1M tokens. A token is a small piece of text, often a short word or part of one.

When a conversation gets longer than the desk, older parts have to be summarised or dropped. Line CLI does this automatically at about 80% full.
